    When running a T5 behind a B motor. I see people are using a AA bell housing. Can a BB used? What is the difference? Another question are the flywheels the same for a model a motor and a model b? Thank You!

    Don't know about the bellhousings but the flywheels are different between the A and B as I understand it.
    I'm going to use B-engine and B-trans in my '28 phaeton.

    For my A I have a B Motor and B trans. No flywheel yet. My friend is the one running a B motor with an Ardun head and wants to run a T. He doesn't do computers. That's why I am asking. Thanks.

    Thank Krylon for making “farm tractor implement red” paint
    If someone tells me they don’t care what color the motor is, I make another tractor.
    I tell them it’s worth 2-3 hp

    Ok, I've been told by my friend and mentor who is helping me with my car that the B flywheel is a bit lighter than the the A. And by the looks of it that seems reasonable.

  8. The B is lighter - the BF more so. An A flywheel won't fit in the B bellhousing without lightening down to the B dimensions. I have about 20 orphaned A flywheels here but the shipping to Sweden would be a killer.

    B flywheel is 10lbs lighter than an A,63 lbs vs 53 lbs..the heavier crankshaft weight is offset by the flywheel reduction.the B Flywheel has two 'steps' on the outside edge,the A has three..

    Mr N,my guess is that there's more rattle can rustoleum on old fords than any other coating..

    So it was good to see and dine with you in Denver Saturday! ...this could have been a topic for discussion & I am glad you are planning on doing this. I don't know the paper answer but I think I would find me a level highway section and benchmark a 1/4 mile and run it with the car.
    It is going to be a combination of engine performance, main box gear split and rear end gear....that would allow for a real performance test. How does it do with the current set up? Do you run out of motor or gear?
    My thoughts....

    Thanks for confirming.
    And I already have a B flywheel for my car so no shipping needed.

    I am not sure about the BB bellhousing but for T-5 conversions people like the AA because it is shorter than a stock A. It allows the input shaft from the T-5 to engage the clutch. I used a stock A bell for my t-5 conversion and had a little adapter shaft made out of a T-5 clutch hub and and an old input shaft.

    I hope this helps. There are more pics in my build thread. There is a link in my signature.

    On 1/8 mile don’t top out in third. I will experiment but not overthink it like I was.
    A veteran racer friend who I shall not name put my car down the 1/8 mile 4times and won the last 3 by a good margin. He sad “I left it 2nd and it kept pulling”. The flywheel bolts were less than hand tight after that.

    My little bit of experience understanding stored energy and Mr Fords desire to dampen torsional impulses with flywheel weight led to 63 lbs. For a street car pulling 10 lbs off by using a B flywheel and a dynamically balanced A crank allows a little better spool up and faster shifts,but is still nice to drive.

    I would believe more rust than paint.........
    Come to find out, I never look at the labels, it is Rustoleum Tractor Farm Implement Red paint.
    Whoda' thunk

    I have never seen a "B" flywheel before, but pretty interesting as I just whittled my "A" flywheel down to 51 lbs.....51.15lbs to be exact, and it looks similar to the stock "B" flywheel. I could have gotten a little more off probably to 48lbs give or take, but my target was 50lbs, I'm not going to worry about the last pound.

    Once you free yourself from the chains of perfection paint and body is fun.

    Not knowing what the flywheel is going in, most will upgrade to a 3 finger 9" clutch.
    If you want to do this, the step can be removed, approx #2.5 and then you can remove a little more from the clutch surface. You will have to drill and tap for the new clutch, not difficult. This is probably the most common conversion. If you need more clutch torque capability some use a diaphragm clutch from the S10 pickup.

    On a side note, what machine are you turning the flywheel on?
    Best, John

    Was that a touch of subtle sarcasm @97 ? I just bought a can yesterday at the local paint store.

    I think the 9" clutch conversion is one of the things that absolutely makes the Model A/B more driveable.
